Support material consists of slides projected by the teachers during lessons.
The material will be provided to students using a Moodle Platform.

The aim of this course is to provide knowledge of technical language and techniques of Design Technology and Industry, with particular regard to the major industry regulations, to introduce the main elements of machines. The course has the following objectives:
- Provide the basic elements of the language of technical communication in industry, in order to put the student able to correctly perform and interpret technical drawings.
- Describe the organs of machines and their modes of representation
- To provide the basics of computer aided design
After completing this course the student will be able to analyze a mechanical draft, drawing up a BOM and to know the rules for the representation of the machines.

No prerequisites are needed.

The course syllabus is dealt with alternating lectures and tutorials.

The examination is performed with a written test in order to verify the ability of the student to analyze a mechanical drawing, drawing up a BOM, and to answer questions relating to the representation of the machine.
